Study Suggests Sugary Drinks May Be “Common Link” Between Dental Erosion, Obesity
UPI (10/28, Dunleavy) reported researchers suggest that dental erosion and obesity may have “at least one common link – sugar-sweetened beverages.” After analyzing “data from 3,541 American adults,” with about two thirds “either overweight or obese, based on body mass index,” researchers from King’s College London found that “overall, more than 12 percent of the adults studied had moderate to severe tooth wear, with an average of 3.4 tooth surfaces affected.” In adults “who regularly drank soda and other soft drinks, the number of teeth affected by wear was 1.4 times higher per sugary beverage consumed per day.”
International Business Times (10/29, Mathew) reported, “The research team concluded the study by stating that consumption of sugar-sweetened acidic drinks is a common cause of both obesity and tooth decay.”
In a release picked up by News Medical (10/28), lead author Dr. Saoirse O’Toole from King’s College London said, “This is an important message for obese patients who are consuming calories through acidic sugar sweetened drinks. These drinks may be doing damage to their body and their teeth.” The findings were published in the journal Clinical Oral Investigations.

6 Ways to Reduce Your Child’s Sugary Snacking
Girl choosing between healthy snack and unhealthy snack When working with her young patients, pediatric dentist and ADA spokesperson Dr. Mary Hayes teaches them this simple, but important, saying: “Sugar is fun to eat, but not good for your teeth!”

That’s because your child might love sweet treats, but the bacteria in his or her mouth loves them even more. “Sucrose (sugar) is the ‘food’ for the bacteria that cause tooth decay,” Dr. Hayes says. “Those bacteria produce acid that etches away the teeth.”

Limiting the amount of sugar your entire family eats is good for your teeth and key to your overall health. Here are some dentist-recommended ways to start saying good-bye to unnecessary sugar throughout the day.

Know the Limits

When choosing a snack, keep an eye on added sugar (sweeteners like corn syrup or white sugar that are added to prepared foods). Naturally occurring sugars are less worrisome, as they are found in healthy choices like milk and fruit.

The U.S. Food and Drug Administration recommends that people age 3 and older should consume no more than 12.5 tsp. each day of added sugar. (The same as one can of soda.) The World Health Organization states that adults should consume no more than 6 tsp. of added sugar, and children should have no more than 3 tsp.

When reading labels, you’ll see sugar is listed in grams. Since 1 tsp. of sugar equals 4 grams, aim to make sure the foods you are feeding your child fall between 12 to 50 grams a day.

The Truth About Juice

Because juice is high in sugar and calories, water and milk are always the best options for your little one. In fact, if your child is under 1 years old, the American Academy of Pediatrics suggests completely removing juice from his or her diet.

Older children can occasionally drink juice, but if they do, there are two things to remember:
Children ages 1-6 should have no more than 4-6 oz. of juice each day, according to pediatric guidelines. Children ages 7 to 18 should drink no more than 8-12 oz. (Many juice boxes are about 6 oz., so younger children should have no more than one per day, and older children no more than two.)
Allowing your child to sip on juice throughout the day puts him or her at higher risk for tooth decay because you’re giving that cavity-causing bacteria more opportunities to eat and produce the acid that eats away at teeth. This can also happen with juice that is watered down. “Even though the volume of sugar has decreased, you’ve added the time that it takes to drink it,” says ADA spokesperson Dr. Jonathan Shenkin.
So what’s a parent to do? Limit the amount of juice your children drink, and always offer water or milk first. If your child does drink juice, serve the recommended, age-appropriate limits at mealtimes only. When your family is done eating, clean up any leftover juice instead of letting your children leave the table with it.

Skip the Soda

Call it soda, call it pop. But sugary, carbonated beverages by any name are bad news for your child’s teeth. “One can of soda is the amount of sugar recommended for three days for a child,” Dr. Hayes says.

In fact, a February 2016 study in the Journal of the American Dental Association found a strong association between sugary drinks and poor dental health in teenagers. Researchers asked teens 14-19 in Mexico about how many sugary beverages they drank, then examined their teeth. They found 31.7% had tooth erosion, which means their enamel had been eaten away. The main culprit? Soda.

Be Picky About Sticky Snacks

If you’ve been under the impression that gummy or sticky fruit snacks are healthy alternatives, you’re not alone. Many parents are surprised to learn they are really closer to candy than fruit, especially when it comes to sugar. “Fruit rollups and other dried fruit snacks are like nature’s candy,” Dr. Shenkin says. “It is like candy, but in some respect it’s worse than candy because it sticks to teeth longer than things like milk chocolate, which is easier to wash away.”

Foods like raisins, which are often promoted as an all-natural snack option, can be troublesome. “The raisin is one of the worst foods because they’re so sticky and they actually adhere to teeth and stay there for an extended amount of time,” he says. “The sugar in that food is being consumed by the bacteria in our mouth during that time.”

Serve Carbs with Care

Whether it’s the crunch or the fact that they’re shaped like their favorite animals, kids love crackers and chips. The truth? “Many crackers are cookies with salt,” Dr. Hayes says. Not only do the carbohydrates in things like crackers and chips break down into sugar, they also tend to get stuck in the tops of your teeth for long periods of time.

Set an Example

You’d do anything for your kids. Now, are you ready to do all of the above for yourself too? Dr. Shenkin says setting an example can make a big difference in your whole family’s health. Eat well, brush twice a day for two minutes and clean between your teeth once a day. “If you want to change your child’s habits, it isn’t just about what they do,” he says. “Do the same thing with them.”


Tobacco Use

Vaping Can Have Similar Effect On Teeth As Cigarette Smoking, ADA Spokesperson Says
Health (8/27, O'Neill) discusses the effects vaping may have on the teeth, featuring information from American Dental Association spokesperson Dr. Matthew Messina. Vaping adds “heat in the mouth,” Dr. Messina says, which “changes the bacterial presence in the mouth. It dries the mouth out.” Dr. Messina adds, “[The] rate of tooth decay increases, sometimes dramatically, if we dry the mouth out.” In addition, vaping can lead to tooth discoloration because of the presence of nicotine, inflamed gum tissue, and bone loss, he says. “It’s important to stress the fact that while vaping is new and is being actively studied, we have to consider vaping and cigarette smoking relatively the same, as far as the effects on the teeth and gum tissues,” says Dr. Messina.
Last week, the New York Times (8/23, Richtel, Kaplan) reported that public health officials announced the first vaping-related death. In a media statement, the Centers for Disease Control and Prevention said the “death in Illinois reinforces the serious risks associated with e-cigarette products.”

[08/15/19]   Prenatal Vitamin D Intake May Reduce Risk Of Enamel Defects In Children, Study Suggests
The New York Times (8/13, Bakalar) reports, “Women who take large doses of vitamin D during pregnancy may be giving their children a lower risk of dental problems,” a “double-blinded clinical trial” suggests. Researchers randomly assigned 623 women into two groups and beginning on the “24th week of pregnancy, one group took two pills daily, one containing 400 units and the other 2,400 units of vitamin D,” while the other “took a 400 unit pill plus an identical-looking placebo.” Researchers “found that children of women who took the vitamin D regimen had a 47 percent lower rate of enamel defects in both permanent and baby teeth than those in the control group.” The study was published in JAMA Pediatrics.

Lack Of Evidence Belies Supposed Benefits Of Charcoal Toothpaste
CNET News (7/3, Capritto) reports on the use of activated charcoal in toothpaste. Though CNET says the ads for charcoal toothpaste “claim you’ll get a noticeably whiter smile after just one use,” in addition to “anecdotal claims that charcoal toothpaste prevents cavities or otherwise promotes better oral health,” there’s “no evidence to support that.” CNET adds, “[T]he evidence is limited, and there’s no proof that charcoal toothpaste actually does the things that the Internet claims it does.”

[06/21/19]   E-Cigarette Explodes In Teenager’s Mouth, Causes Jaw Fracture
The New York Times (6/19, Kaplan) reports on a 17-year-old who, in March of 2018, had an e-cigarette explode in his mouth. The teenager “had a major fracture of his lower jaw, including about a 2-centimeter piece that had exploded and was missing, and he was also missing multiple teeth.” One physician “said that she believed the injury was caused by an exploding battery but that she was not certain.” The case was published on Wednesday in the New England Journal of Medicine.

Poor Oral Health Associated With Several Health Conditions, Studies Suggest
Care2 (6/15, Syuki) highlighted several studies that suggest poor oral health is associated with Alzheimer’s disease, pancreatic cancer, and other health issues. For instance, the article reported that research suggests periodontitis is associated with the development of Alzheimer’s disease, and in another study, researchers found “a type of bacteria (Porphyromonas gingivalis) associated with gum disease” in the brains of patients with Alzheimer’s disease. The article discussed several other studies, including a study that suggests the bacteria involved in periodontitis may “play a part in the onset of pancreatic cancer.”

Americans Consume 74,000-121,000 Microplastic Particles Annually, Study Shows
CNN (6/5, Scutti) reports “Americans eat, drink and breathe between 74,000 and 121,000 microplastic particles each year depending on their age and sex, new research suggests,” and “those who exclusively drink bottled water rather than tap water can add up to 90,000 plastic particles to their estimated annual total.”
HealthDay (6/5) says the study is an “evidence review” of 26 other studies. Per HealthDay, “it’s tough to accurately calculate the amount of plastic people consume, noted the lead author of the new study, Kieran Cox,” as “a person’s microplastics consumption rises based on personal food choices they make.”
The Guardian (UK) (6/5, Carrington) reports the average person “eats at least 50,000 particles of microplastic a year and breathes in a similar quantity, according to the first study to estimate human ingestion of plastic pollution.” However, the “true number is likely to be many times higher, as only a small number of foods and drinks have been analysed for plastic contamination,” according to the paper published in the journal Environmental Science and Technology.

Teenagers Buying Vaping Products On eBay, Other Online Marketplaces
The Verge (6/5, Kelly) reports that “as government regulators move to crack down on youth vaping, eBay and other online marketplaces are still awash with bootleg Juul pods.” The article says that the marketplaces disobey “most platform rules.” Still, nothing “has managed to block the sales entirely, suggesting that regulators may face an uphill battle as they try to curb the teen vaping epidemic.” Both “Congress and regulators are...fed up with teen vaping and have begun to ramp up efforts to curb youth tobacco sales, including Food and Drug Administration restrictions on flavored products.” It is “common knowledge that many of the pods sold online are fake and could contain harmful ingredients, but users continue to purchase them and recommend eBay as a source for underage users.”
